A strain of Saccharomyces cerevisiae (LPB-SC) was selected and fermentation conditions were defined at the laboratory scale, which included the medium with Soluble solids concentration of 30% (w/v), without pH adjustment or supplementation with the mineral sources. The kinetic parameters - ethanol productivity of 8.08 g/L h, Y-P/S 45.4%, Y-X/S 0.815%. m 0.27 h(-1) and mu(x) 0.0189 h(-1) - were determined in a bench scale bioreactor. Ethanol production yields after the scale-up were satisfactory, with small decreases from 169.8 L at the laboratory scale to 163.6 and 162.7 L of absolute ethanol per ton of dry molasses, obtained at pilot and industrial scales, respectively. specialized Soybean molasses Bio-ethanol Pilot scale Industrial scale Saccharomyces cerevisiae 084 99 17 8156-8163 2008 0960-8524 https://www.documentation.ird.fr/hor/fdi:010042757 10.1016/j.biortech.2008.03.037 0960-8524 [F B010042757] https://www.documentation.ird.fr/hor/fdi:010042757 https://www.documentation.ird.fr/intranet/publi/2008/09/010042757.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-10-06 2017-08-23 fdi:010042757 fre
